When I send video source that has an alpha channel to a jit.gl.videoplane, the "color 1. 1. 1. $1" message will allow me to fade the plane in and out.
However, when I apply a shader to the texture of the videoplane (using "sendtexture" and "shader" messages), it's no longer possible to control fading with the "color" message anymore.
The effect of the shader is visible, but the "color" message no longer produces a fade.
Perhaps the alpha information is getting lost through the shader? It seems the same for the 5 or 6 different shaders I tried.
